Safety

Description: A) Collect and document broken rail/service failure to determine “why was it missed given the current ultrasonic and grinding practices?” and B) Quantify a severity of surface fatigue cracking at which the effectiveness of ultrasonic detection is seriously compromised.

Status: Earlier work at Chalmers reviewed the characteristics of transverse defects (see link). Research and data plans are being developed for the next stage of work. WebEx planned for Nov/Dec 2017
